• Added BinaryField for storing binary objects (bytes).
• Changed TextField to use LONGTEXT for MySQL to allow for larger than 64KB of text.
• De-duplicate index if specified on both index=true and as part of indexes
• Primary Keyed TextField is marked as deprecated.
  We can't guarnatee that it will be properly indexed or unique in all cases.
• One can now disable the backwards relation for FK/O2O relations by passing related_name=False
• One can now pass a PK value to a generated field, and Tortoise ORM will use that as the PK as expected.
  This allows one to have a model that has a autonumber PK, but setting it explicitly if required.
